These high-capacity pipes are supplied with a wide selection of fittings and are available in either a grey transit primer or in the Premier Extra gloss black painted finish. Our cast iron rectangular rainwater pipes are offered in a variety of lengths and this version is the plain variety without the fixing ear on the collar.

The rectangular cast iron downpipe offers a solution to projects which need to move large quantities of water from the roof to the ground. Not only are these cast iron pipes effective at moving rainwater, they make a stunning architectural feature which not only look good but also offer benefits that no other rainwater system can match.
Our cast iron rainwater downpipes offer unrivalled strength, durability, low operational noise levels, and environmental benefits and when properly maintained provide a lifespan in excess of 80 years.
Our standard range of cast iron rainwater downpipe profiles includes round, square and rectangular. In addition to these cast iron profiles, our range can be complemented with unique bespoke products which can be manufactured to meet your size and design requirements.
Some of our cast iron products such as the cast iron square rainwater pipes are made to order. They are available within the Metal & Glass cast iron range but need to be cast or fabricated with timescales being slightly longer than our off-the-shelf stock products. They can be ordered securely via our website in exactly the same way as ex-stock products. These cast iron made-to-order items are available in both the grey primer and gloss black painted finish.
We can also offer bespoke hoppers to match original designs as well as adapt existing cast iron hoppers by changing outlet sizes and positions.
